The COVID-19 pandemic has led to the development of alternative means of accessing unplanned care in order to avoid unnecessary ED presentations and hospital admissions. We explore the definition of emergency medicine, which patients are better served by accessing unplanned hospital care via alternative pathways, and the concept of emergency care completion.

Case ReportsSengstaken-Blakemore tube in critical upper gastrointestinal bleeding: Implications for aeromedical retrieval.
Sengstaken-Blakemore tubes (SBTs) are rarely used in Australia, because of improved access to endoscopy and interventional radiology, as well as overall lower rate of variceal haemorrhage from improvements in primary prophylaxis. SBT's use is associated with significant rate of serious complications, such as oesophageal perforation, mucosal necrosis, aspiration pneumonia and respiratory compromise secondary to external compression of the trachea. As such, SBT is currently only recommended for use in life-threatening variceal haemorrhage, where endoscopic, embolization and pharmacologic therapy have been unsuccessful or are unavailable. ⋯ We present a case of SBT insertion in retrieval medicine and discuss placement in the management of an unstable upper gastrointestinal bleed, complicating factors such as lack of radiology to confirm balloon position, the impact of flight altitude on balloon pressures, the maintenance of traction in flight and logistics of long flight times across the state of Queensland. This is the first case report of SBT use in the Australian aeromedical environment. It is also the first one where SBT has been used for duodenal bleeding, although the source of bleeding was unknown prior to insertion.

Case ReportsToo much of a good thing: Bicarbonate toxicity following treatment of sodium channel blocker overdose.
Although sodium bicarbonate can be a life-saving antidote for patients with overdoses resulting in sodium channel blockade, there has been a concerning rise in cases referred to the Poisons Information Centre where inappropriately large doses of bicarbonate have been used resulting in iatrogenic harm. We present a series of three clinical cases where excessive bicarbonate was used to treat poisonings and discuss our approach to managing cardiotoxicity secondary to sodium channel blockade. Serial blood gas analysis should be performed when using bicarbonate to ensure pH targets are met and severe alkalaemia, hypernatraemia and hypokalaemia are avoided. We encourage clinicians to contact the Poisons Information Centre (13 11 26) or their local clinical toxicologist when managing patients with life-threatening sodium channel blockade.
